/* Puro Classico design system v9 (ds.css), 29 Oct 2026
   One stylesheet for every server-rendered page (product, brand, category, agent, best, guide and tool pages) and the
   static pages (how-to-order, privacy, terms). Look: shadcn/ui "neutral" with Inter, light / dark / system.
   Theme: <html data-theme="light|dark"> is the visitor's choice (localStorage "manifest.theme", shared with the app);
   no attribute means "system" and the prefers-color-scheme query decides. Rules: see DESIGN.md. */

/* v9 tools kit */
/* tools kit (tk): shared UI for /tools and every /tools/<slug> page. Spec: r2/TOOLS_SPEC.md section 1.
   Shared helpers in functions/_lib/site.js (import them in tools9.js too): toolShell({slug,name,h1,lead,trust,ui,about,
   faq,title,desc,jsonld,wide,bc}) builds the whole page; tkHero(), tkRelated(path), tkCopyBtn(label, attrs), TK_ICONS,
   TK_I (check, copy, alert, x, link, share, ext, right, prev, next, image), TOOL_ONE, TK_TRUST and TK_JS (client
   helpers, window.TK: esc, say, copy, debounce, qs.get/set, recent, seg, pasteBtn, ago, store, sess).
   Page shell (same on all 5 tool pages):
     <div class="tk-page">  breadcrumb, <header class="tk-hero"> [.tk-hero-ic] h1 ([.tk-name] inside) .lead .tk-trust </header>
       <section class="tk-card"> fields ... <div class="tk-out" data-state="empty|loading|error|success"> </section>
       <section class="tk-recent"> ... </section>
       <div class="tk-below"> h2 How It Works + .prose, FAQ, .tk-related </div>
     </div>
   Rules: one black pill (.btn.primary) per visible state inside a card; segments are never black; no red;
   errors are neutral (.tk-alert); never nest a bordered card in .tk-card (results use .tk-res fill).
   Legacy .tool rules above stay until tools9.js stops using them; do not put .tool and .tk-card on one element. */
